339 - Eat Food, Mostly Plants: Cutting Through Nutrition Nonsense with Dr. David Katz

When the loudest voices in health are selling confusion, fear, and the next quick fix, it's hard to know what — or who — to trust. That's exactly why conversations like this one matter. Dr. David Katz has spent decades cutting through the chaos with uncommon clarity. A renowned physician, bestselling author, and one of the most influential thinkers in nutrition and preventive medicine, his work has helped millions rethink the very basics of how we eat and how we live.

In this very special episode, he unpacks what determines human health, what real nourishment looks like, and why choosing it now is more radical — and more necessary — than ever. If you've ever wondered what's true, what's marketing, and what actually moves the needle on well-being, this is a must-listen conversation.

What we discuss in this episode:

• The nutrition pattern humans are biologically built for.

• Why fiber is non-negotiable for long-term health.

• Why smart regulations save lives — and what happens when they're missing.

• How Big Food and Big Tobacco use the same playbook to keep us hooked. 

• Methylcellulose: what it is, where it comes from, and why it's misunderstood.

• Why beef tops the list as the most environmentally destructive food.

• The fundamentals of longevity that anyone can put into practice.

• The biggest misconceptions most people have about staying healthy.
